The SfbDns .NET class library offers a number of classes that make the work of querying DNS servers for resource record types defined by RFC-1034 and RFC-1035 more easily. You can easily retrieve the list of available DNS servers in your network, send a constructed DNS request message to a DNS server and process the fully parsed response message. The library offers the flexibility, ease of use and rapid development features of a component without the complexities of working with the native socket class or in-depth knowledge of how the Domain Name Services are implemented.
